HAND-STAMP.

Specification of Letters Patent.

Patented Nov. 6, 1917.

Application filed March 28, 1912. Serial No. 686,930.

To all whom it may concern Be it known that I, LoUIs K. Sporronn, a citizenof the United States of America, and a. resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hand- Stamps, of which the following is a specification.

My invention relates to improvements in that class of hand stamps in which it is desirable to adjust or change part of the printing characters, and the object of the invention is to provide a stamp of this character which will be capable of ready adjustment and'one which can be readily assembled and extremely durable in use.

The invention consists in the construction which is hereinafter more particularly described and illustrated, in its preferable embodiment, in the accompanying drawings.

Referring to the aforesaid drawings:

Figure lis a perspective view of a hand stamp made in accordance with my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a vertical central section showing, in dotted lines, the parts thrown in position for adjustment.

Fig. 4 is a perspective view of a blank.

Fig. 5 is a perspective view of the frame made out of the blanks shown in Fig. 4E having the sheet metal frame or drum connected therewith.

Fig. 6 is a sectional view intended to show the spring catch.

Fig. 7 is a sectional detail.

Fig. 8 is a perspective view of the die plate detached.

Fig. 9 is a perspective view of the modified form.

Referring now to the details of the drawings by numerals: 1 designates the main frame of what is known as the tumbler form of hand stamp and, as usual, comprises a handle 2 for depressing the yoke 3 which is connected to the frame, hereinafter described, for supporting the printing char acters 4. In the preferred embodiment of my invention, each of the side members of the frame 1 is provided with a slot 6 in which travels a lug 8 (Fig. 7) projecting at right angles from an arm 10 formed on or rigidly connected with the lower end of the yoke 3. It will be understood that these parts are exactly alike on each side of the main frame 1. It follows from the construction just described that whenever the handle 2 is depressed the yoke 3 is caused totravel in an absolutely vertical line owing to the fact that the lugs 8 slide within the vertical slots 6. As a modified construction, I have illustrated the yoke 23* in Fig. 9, as having two arms 12 and 14 on opposite sides of the end of the yoke, these arms 12 and 141 having flanges 16 and 18 which embrace the vertical edges of the main frame 1 in said figure and thus cause the yoke 3 to travel in a vertical line without employing a slot 6 such as shown in Fig. 1. I consider this modified construction as equivalent to the construction shown in Fig. 1, although I prefer the form shown in Fig. 1 as being simpler.

Heretofore it has been common in hand stamps of this character to connect the ends of the yoke 3 with the frame carrying the die plate and the printing characters by means of a rod or cross bar which passes completely through the stamp, from one end of the yoke to the other end of the yoke 3, this construction being shown in my Patent No. 668,021. It has also been proposed to employ a common screw on each side of the frame to secure the end of each end of the yoke 3 to the die plate of the frame carried thereby. To avoid the. use of both of these constructions, I employ the construction shown particularly in Figs. 1 and 7 As there shown it will be observed that I have employed a short stud 20 having an annular flange 21 near one end thereof. The end 22 of the stud 20-is inserted in an opening in part of the movable frame 26 and is riveted therein as clearly shown in Fig. 7, the annular flange 21 serving, when the parts are in use, to properly space the movable part of the frame 26 from the side of the main frame 1. The stud 20 will project through a grooved slot 28 in the side of the main frame 1 and will pass through a horizontally disposed slot 30 formed in the lower end of the yoke 3 and its arm 10, as seen in Figs. 1 and 7, a ring 32 being clamped in the groove 34 in the end of the stud 20 to hold the parts in position. In order to prevent undue fric tion, I prefer to place an anti-friction roller 33 around the stud 20, said roller projecting into the slot 30 of the arm 10, as illustrated in Fig. 7. It has hitherto been impossible to use any kind of a stud such as the one 20 in Fig. 7, for the reason that the parts could not be properly assembled. make the assembling possible and easy, 1 form the lower end of each side of the frame with an extension having therein a continuation of the slot 28, this extension being bent at right angles to the side fran'ie so that the slot in the extension is at right angles to the slot in the side frame. This slot just the tn'oper s ze to permit the passage of the stud through it, and after the die plate with the studs thereon is slipped in position and the studs are above the flanged extensions 36, the ends of the yoke 3 may be slipped over the ends of the studs, and the rings may then be clamped in the grooves of the studs and the various parts properly secured together. The flanges 40 and 42 'n'ojecting from the die plate i' are slotted so that the sides of the flanges a and L2 straddle blocks 6 and 48 which are journaled on headed pins 50 and 52 secured to the side frames as shown in Fig. 2, (seealso Fig. 8). hen the handle 2 and its yoke 3 are depressed so that the die plate at is caused to descend, the yoke, as before stated, is caused to descend in a vertical line owing to the fact that the end of its arm 10 fits within the vertical slot 6. At the same time, the studs projecting from the flanges 4:0 and d2 of the die plate tat are given a V movement by the shape of the slots 28 which cause said studs to slide in the slots 30 of the arms 10 at a time when the die plate is near the center of its movement. The result of this movement is that the flanges i0 and of the die plate and their journaled blocks :6 and 4C8 are caused to partially rotate on the headed pins and 52 so that the die plate is caused to tumble from the inking to the printing position. By this tumbling movement the die plate is given a truly vertical movement both at the beginning and end of its stroke owing to the fact that both ends of the grooved slot 28 are in avertical line. Hence the die plate is given an abso lutely vertical movement at the time the printing characters touch the inking pad and also an absolutely vertical movement at the time the printing characters are in the act of printing.

The die plate H has two lugs 56 projecting therefrom and to these lugs is pivotal 7 secured a frame 58 which I prefer to make of one piece of metal from a blank such as shown in F ig. 4. This blank is so manipulated that it is formed into the form shown in perspective view in Fig. 5 and as there shown it has two side arms 59 and 60 which are pivotally connected to the lugs 56 projecting from the die plate t e. Rectangular i ns 62 on opposite sides of the blank in t are formed to make tubular G and (it which are screw threaded s ho to receive screws (36 and 68, these screws adjustably securing a sheet metal form or drum 71) between the two arms 59 and ($0 of the frame 58 as shown in Figs. and he member 71 of the blank iown in Fig. -lforms the connecting web 72 shown in Fig. 5, and the projections 73 of Fig. -i are bent downward to the position shown at H of Fig. 5 for the purpose of having socured to them a spring catch 80. This spring catch has a resilient thumb piece 81 at one portion thereof and a locking flange 82 at the other end thereof, said flange being in just the proper position to lock over the flange 86 of the die plate M as indicated in Fig. 6. The construction is such that whe the operator presses witn his thumb or fluger against the member 81, the flange 82 of the spring catch is caused to move from the position shown in fuli lines to the position shown in dot-ted lines in Fig. 6 thus loosening the catch of the die plate and permitting the frame 58 with its form or drum 70 to be moved on the lugs 56 as a pivot. The form or drum 70 is for the purpose of supporting the printing characters at and nothing new is claimed in either the f nine or the printing characters, they being very clearly shown in my Patent No. 668,021 of Feb. 12, 1901.

The die plate 44 is provided with a thin sheet metal plate 90 shown best in Fig. 6 having two flanges 91 adapted to hold the movable type in alinement.

The detailed description has been given in such detail that it is believed that a description of the operation is unnecessary.

It is obvious that changes and other modifications may be made besides the one shown in the drawings and reference should therefore be made to the accompanying claims to determine the scope of the invention.
